AFCO is proud to announce the new completely redesigned 85-88 Series Monotube bulb shocks. These shocks have a completely new internal valve design that uses deflective disk technology and all new fully CNC machined pistons that were developed using EMA dyno pressure balancing technology. With two piston options, a highly tunable base valve, and jetted shaft options, AFCO can customize any shock valving for your race car. This shock series comes with a 1/2" shaft for low rod pressure and gain, a smaller, light bulb design for weight reduction and a-arm clearance, nickel plated exterior for durability, and a universal style fill port option to make it IMCA legal or Schrader valve where rules allow. How to read and specify your part number: The first two digits are the shock series (example: 85), the third digit is the stroke length (example: 7), the fourth digit is the compression range (example: 3), the final digit is the rebound range (example: 3).
